CS4365
4.14.2.1 I2C Write
To write to the device, follow the procedure below while adhering to the control port Switching Specifica-
1. Initiate a START condition to the I2C bus followed by the address byte. The upper 6 bits must be
001100. The seventh bit must match the setting of the AD0 pin, and the eighth must be 0. The eighth
bit of the address byte is the R/W bit.
2. Wait for an acknowledge (ACK) from the part, then write to the memory address pointer, MAP. This
byte points to the register to be written.
3. Wait for an acknowledge (ACK) from the part, then write the desired data to the register pointed to by
the MAP.
4. If the INCR bit (see Section 4.14.1 ) is set to 1, repeat the previous step until all the desired registers
are written, then initiate a STOP condition to the bus.
5. If the INCR bit is set to 0 and further I2C writes to other registers are desired, it is necessary to initiate
a repeated START condition and follow the procedure detailed from step 1. If no further writes to other
registers are desired, initiate a STOP condition to the bus.
4.14.2.2 I2C Read
To read from the device, follow the procedure below while adhering to the control port Switching Specifi-
cations.
1. Initiate a START condition to the I2C bus followed by the address byte. The upper 6 bits must be
001100. The seventh bit must match the setting of the AD0 pin, and the eighth must be 1. The eighth
bit of the address byte is the R/W bit.
2. After transmitting an acknowledge (ACK), the device will then transmit the contents of the register
pointed to by the MAP. The MAP register will contain the address of the last register written to the
MAP, or the default address (see Section 4.14.1 ) if an I2C read is the first operation performed on the
device.
3. Once the device has transmitted the contents of the register pointed to by the MAP, issue an ACK.
4. If the INCR bit is set to 1, the device will continue to transmit the contents of successive registers. Con-
tinue providing a clock and issue an ACK after each byte until all the desired registers are read, then
initiate a STOP condition to the bus.
5. If the INCR bit is set to 0 and further I2C reads from other registers are desired, it is necessary to initiate
a repeated START condition and follow the procedure detailed from steps 1 and 2 from the I2C Write
instructions followed by step 1 of the I2C Read section. If no further reads from other registers are de-
sired, initiate a STOP condition to the bus.
